I dont think I've ever gotten the badge in the mail, maybe I have I dont know. When your there just go to the registration and sign in if you havent gotten it yet, they are not likely to turn you away.
got my package yesterday. contains the tentative schedule of events, and my badge... what will happen later (based on past years) is i'll get there, stand on a short line with ppl who have gotten their stuff through the mail, and be handed a goody bag along with something to put my badge in / wear around my neck.
I just received them in the mail, they give you stickers with your name on it. I have in the past shown up at the gate and registered as mentioned above, and they give you a badge, there was no problem at all to enter.
interesting. i have been to 4 of the expos and never recd the badge in the mail. hmmmm. i must be on the BLACK LIST. surf
nice to see a few new faces presenting at this expo to bad the rest of the crowd seems to be selling the same old voodoo
